Good idea. If it does, a configuration snippet in /etc/X11/xorg.conf.d could be helpful. The recommendation to not use any configuration at all is often best, but in multi monitor setups I am using some configuration snippet in said directory on the workstation at work since quite some time, cause automatic setup didn´t work for me either. Before that trying to setup up things with krandrtry might help. But then this settings might only be specific to one desktop environment, namely KDE in this case. A configuration snippet for X.org should work in any desktop environment / session. Reading recommendation: http://wiki.debian.org/XStrikeForce/HowToRandR12 So place something along the lines of: --------------------------------------------------------------------- Section "Device" Identifier "My Graphic Board" ... Option "Monitor-LVDS" "Internal Panel" Option "Monitor-VGA" "External VGA Monitor" EndSection Section "Monitor" Identifier "Internal Panel" ... EndSection Section "Monitor" Identifier "External VGA Monitor" ... EndSection --------------------------------------------------------------------- in /etc/X11/xorg.conf.d/display.conf (or something like this). Adapt monitor output names to what xrandr tells you as output names. You can hardcode resolutions as needed. I would only do that if automatic detections fails tough. If necessary raise the maximum virtual size. All described on that wiki page. Golden rule: Only configure that which doesn´t work out of the box. Leave everything else out. That approach works really nicely for me since the time X.org was changed to configure almost everything automatically. If need be I could dig out my configuration snippet when I am back at work next week. > - Does the same happen with Squeeze stock kernel?
